I have had the same email address since 1995. I have been buying things online since that was available. These facts mean that my email address is on every spam list in the world, and that every merchant I’ve ever bought anything from as well as all the spammers and scammers send me at least one and often more than one email every day.
Multiple levels of filters and unsubscribe links mean that my morning inbox is only full, not bursting, but even so, I wind up just selecting everything and tossing it into the trash. I love the subject lines that tell me not to miss out on this opportunity, which is almost gone. I feel encouraged by them, and press delete even faster.
